4nm Colloidal Gold-AffiniPure™ Rabbit Anti-Horse IgG (H+L) (LM Grade)

Whole IgG antibodies are isolated as intact molecules from antisera by immunoaffinity chromatography. They have an Fc portion and two antigen binding Fab portions joined together by disulfide bonds and therefore they are divalent. The average molecular weight is reported to be about 160 kDa. The whole IgG form of antibodies is suitable for the majority of immunodetection procedures and is the most cost effective. LM Grade colloidal gold reagents are intended for light microscopy and immunoblotting. Since signal intensity is relatively independent of particle size when silver enhancement is used, we offer 4 nm particles because this size may penetrate tissues better than larger particles. The 4 nm size may be used for electron microscopy in studies that require smaller particles since they are relatively uniform in size (coefficient of variation less than or equal to 15%), though small aggregates are not removed from this grade. Therefore, our 4 nm particles should only be used for electron microscopy with the understanding that the presence of small aggregates may give misleading results.
